We can see how this Google-empowered front-end framework has, in a short time, become the winning choice for app development as compared to other frameworks. So, in this blog, we will outline the reasons why this framework is a good choice over other frameworks. Let’s get started.

Why Angular Framework is Highly preferred over other Frameworks?

Outstanding Productivity and Simplicity of Use

Angular is quite simple to use due to the availability of high-end features. Angular has a component-based model that facilitates the reusability of components inside the app. These features significantly reduce the efforts of an AngularJS app developer for coding the applications. Also, AngularJS has customized IDEs that help the developers to track any errors instantly. This framework has numerous templates for the faster development of the UI. Another feature- CLI i.e. Common Line Interface in this framework lets the developers attach the components and create applications faster.

Easy Integration with Other Libraries

This is one of the best benefits that this framework offers. Angular integrates easily with other libraries, especially when it comes to web development projects, thus making the development speedy. When Angular app developers use various object-oriented MVC frameworks for server-side development, the integration of AngularJS for client-side development becomes simpler.

Strong Support from Google’s Community

It is supported and maintained by the Tech giant- Google. It is one of the most active communities of talented developers who are capable of resolving any issues during the app development process. So, the community provides excellent support to anyone and everyone having any technical issues. This is indeed a boon for every front-end web developer working with Angular. Also, this community hosts conferences and invites global IT companies that introduce modifications and advancements in the framework.

Now let us have a glance at some technical goodies that Angular offers:

MVC Architecture:

Angular comes with an MVC i.e. Model View Controller architecture. Using the MVC, the AngularJS developers can create an application in three separate layers and then merge the codes together. Also, this architecture allows synchronizing the data automatically and reduces complexity while coding. Thus, it becomes a time and effort-saving process altogether.

Two-way Data Binding Potential:

This is an amazing feature that allows the modifications in the user interface to immediately reflect in the applications. Any module changes, user actions, browser events, etc. in the framework gets updated effectively across the app. The developers don’t need to save the links to DOM elements as they can be used immediately. Also, low-level constructions don’t need to be used.

Declarative Coding Style:

Angular’s Declarative coding paradigm is used for the creation of commonly accessible platforms. This includes only the code essential for producing necessary outcomes which makes reading and understanding the code easier and also makes the code lightweight.

POJO Model:

The Angular framework makes use of all objects that are POJO i.e. Plain Old JavaScript Object. This model provides all the standard JavaScript functionalities for manipulating objects. It offers spontaneous and well-planned objects, so, the developers don’t need any extra getter and setter functions.

Directives:

Angular uses HTML which is a pattern language and has the facility of directives. As a result, the AngularJS app developers can easily build new HTML custom directives and code more effectively. It also improves code readability.

Single Page Application (SPA) Features:

This framework is packed with a host of SPA features which gives more control to developers over form validation abilities. SPAs allow easy creation and control of online forms. This results in productive outcomes and gives developers the freedom to modify the behaviour of HTML elements in the UI.

The Facility of Using Filters:

AngularJS comes with a directory of filters consisting of filters like Currency, Number, Date, Uppercase, Order By, etc. Also, in case more filters are required, developers can quickly register a new filter factory. The filters are quite helpful while developing database search functionality or while presenting large data chunks to the users.

RESTful Functionality:

AngularJS supports REST functionality in the ngResource module which again contributes to the building of a quality application while saving the developer’s time.

Other Technical Benefits:

Along with the aforesaid benefits, Angular app development also provides a few other advantages. It allows the creation of a captivating, user-friendly, and lightweight user interface. Moreover, it enables the creation of several new modules for a single application to ease out the development process. Furthermore, it comes with an in-built unit testing module which reduces the unnecessary wastage of time. This enables the developers to get real-time information about the projects.

Final Words:

We have seen the significant reasons why Angular app development can be chosen for your next project. Although Angular may not be the best-suited option for every kind of requirement in the market, it is undoubtedly one of the best technologies for creating a wide range of feature-rich and high-quality applications for several industrial verticals.

With this, we have come to the end of this blog and would like to know your vital thoughts in the comment section.

What are the Best Practices to be implemented in an Angular App Development Project? - Part I

Angular is one of the most popular MVC pattern MVVM frameworks of the 21st century. Developed by Google, Angular is significantly used for building dynamic mobile, web, desktop apps using TypeScript, and HTML.  The initial version of Angular was Angular JS. AngularJS development had created ripples in the software world when it released. Furthermore, this proactive team kept releasing updated versions at regular intervals to keep up with changing times.  Recently, its latest version Angular10 was released in the market which created a buzz in the software world.

But to meet the high-end requirements of modern-day users, it is essential to not only use the next-gen framework like Angular but also follow a certain set of standard development practices. So in this blog, we have enlisted some of the top Angular app development practices that developers can learn and follow. But before we get started, let us have a quick look at the benefits of following these practices, rather tips.

Noticeable Benefits of Following the Angular Development Best Practices

• Helps in Creating a Clean Code
• Aids in Maintaining the Coding Standards
• Helps in Minimizing the Developmental Time
• Ensures a Minimal Score on the Bugs and Issues
• Ensures Improved Performance of the End-product
• Makes Code Management and Debugging Easier

Highlights of the Top Angular App Development Practices

Rules to follow for Angular Coding Styles

Following certain standard coding styles instead of the common styles during Angular app development can ensure the writing of simple and adaptable code and a good user-experience. Here are the rules to be followed for Angular coding styles:

• The code per function shouldn’t exceed 75 lines
• The code per file should not exceed 400 lines
• It is good to declare the values of variables with ‘const’ if those values are intact
• While sharing feature area for all slider components, developers should use a custom prefix
• You can use shortcuts for files with similarly naming conventions. For instance, you may use hero.component.ts|html|css|spec for naming different files with the same names
• In case you usually prefix the names for database, table, field, etc., avoid this practice for Interface names like AbastractShape and iShape
• Apply single responsibility symbol to services, components, and symbols since it allows creating a more readable and cleaner app format.

Best Security Practices in Angular

Security is of utmost importance in any application. In Angular, security lapses can result in a dangerous threats, for instance, cross-site scripting. This issue can result in the passing of controls on the client side resulting in the alteration of the web pages. For avoiding such attacks, the developers should be aware of some security practices in the Angular framework as mentioned below:

• Maintaining the Angular Libraries on Regular Intervals
• Updating Angular libraries for every new update from Google
• Preventing the XSS cross-site security issues

For doing this, it is necessary to consider the measures like DOM sanitization service, Offline template compiler, sanitization and security contexts, context security policy, etc. These will help to keep the attackers away from client-side apps ensuring higher security.

Routing in Angular and related Practices to Consider

Routing in Angular is performed to either display or hide components as and when needed by the users. Routing makes the components available for the development process whenever required, thus reducing constant trips to the server. However, bad routing practices can result in disorganized Angular apps at some point. So, for ensuring these issues don’t exist, the developers need to understand some basics about adding templates and components into the app along with the appropriate functioning of the routes. Have a glance at the best practices concerning Angular routing:

• Developing the routes module wise
• Routing with lazy loading
• Organizing routes guards
• Lazy loading routes with Preload

Preventing Observable Memory Leaks

Unlike any other framework, Angular, too, has observable memory leaks. Observables are of great use in Angular as they help in streamlining important data. But at the same time, leaks in observables can cause critical issues in mobile app development. Please follow the below-mentioned tips to avoid these leaks:

• Use ‘async pipe’: these are built-in attributes that come in handy when the developers need to mark the components for emitted values. Also, they unsubscribe automatically from observables and thus prevent unnecessary memory leakages.
• Use ‘take(1)’: This is an operator that allows you to get the data just once and helps to easily avoid memory leaks.
• Use ‘takeUntil’: This is another operator that should be used when you wish to monitor second Observables and destroy the subscription; once the Observables gets completed or emits the value; thus, preventing the Observables to be leaked.

Usage of Template Directive

In Angular, ‘ngFor’ comes as a built-in template directive and is used for building new templates in the applications for every item. So, the Angular developers can rather use ‘trackBy’ directive every time they use ngFor. So, instead of rendering the complete DOM tree, ‘trackBy’ will help in creating customized and unique identifiers for every item.

Utilizing the most powerful accessibility tool- Angular CLI

Angular Command-Line Interface (CLI) already follows all the standard practices during Angular app development. It eases out the development process. It helps to test, debug, maintain, and deploy the applications. So, the developers should use it for developing an initial-level structure for the Angular app. They must use Angular CLI for the generation of new modules, directives, services, components, pipes, classes, etc. while creating any files and folders, instead of doing it manually. The usage of this interface decreases JavaScript fatigue and complexity.

Here is a detailed blog on other vital tools used in Angular for creating an outstanding application.

A Few Other Recommended Practices

• Naming Conventions for readability and maintainability
• Maintaining the folder structure properly
• Utilizing service workers for ensuring that the apps become highly responsive
• Isolating all the API hacks in one place
• Breaking down the larger components into multiple smaller components
• Ensuring proper documentation of code, every variable, and the methods used
• Using state management libraries for managing state transitions

In our upcoming blog, we will explain these practices in detail and also include some more tips and practices that all the Angular development services should follow. Also, here is our blog on the “Potential mistakes that developers must avoid during Angular development!”

Key Takeaways:

For designing a comprehensive application that becomes lucrative as well as popular, it is essential to implement the best developmental methods. So here, we have mentioned some of these methods which are tried and tested by the experienced Angular developers who have worked on versatile projects for years. Every Angular/Angular JS app development company should consider these tips and train their developers beforehand to refrain from any major mistakes in the projects.

Mistakes to be Avoided while Developing Apps with Angular!

 Angular is one of the most popular JavaScript frameworks, which offers myriad benefits to businesses worldwide. Most businesses prefer using Angular for mobile app development. Numerous giants in the corporate world have used Angularjs app development services for a wide range of projects. Take a look at some examples:

•  Video-streaming applications like NetFlix and YouTube                  
•  Online Payment application like PayPal
•   Travel application like JetBlue
•   A User-review application like GoodFilms
•    eCommerce applications like Land send, iStock, etc.
•    Job-portal like Upwork

Moreover, it is being predicted that Angular’s demand is going to rise further in the coming years. We can see that Angular’s future looks bright.

But despite the ever-increasing demand and popularity, there are some flaws in this framework like any other framework As such, developers tend to commit certain errors that may ruin your project. So, Angular developers and Angular development services must be aware of these common development blunders so that they are able to create top-grade applications.

In this blog, we have outlined the most common mistakes committed by Angular developers during the mobile app development process. So let’s get started.

Noteworthy Mistakes that Angular App Developers tend to commit

Direct Manipulation of DOM

A common blunder that the developers tend to commit is making changes directly in the DOM. While changing the titles in pages or adding images, some developers may make modifications directly in DOM. But it is considered a bad practice. The DOM is a browser-specific API. It may tightly couple the Angular app’s code with the browser and this won’t allow the developers to target any other rendering environment later.

Lack of knowledge of Important Tools

Knowledge of the important Angular tools is a basic requirement that an Angular app development company must look for while hiring developers.

Effective usage of the available Angular development tools like Protractor and TestWhizin Angular helps in successful project development. Lack of knowledge on any of these tools or inability to use them can result in critical issues sooner or later. It affects project management, error handling in the project, the performance of the end product, and much more.

Improper Code-organization

In Angular, organizing the code into small chunks is considered beneficial as it simplifies the development process and also helps to track any errors and resolve them easily. This approach is much useful when several developers work on the same project. But since this framework uses MVC architecture, at times the developers may add excessive code to a single controller. Such an improper distribution of code may create issues in the later stages of development.

Cleaning up the Subscriptions

Unsubscribing to the unnecessary and older subscriptions is also a vital step in Angular development. The developers must clean up such subscriptions from time-to-time as these can cause a threat to data security and lead to several other issues. They should also avoid new subscriptions constantly.

Declaring Functions Incorrectly

Sometimes, the developers fail to assign the functions to a specific variable. In such cases, the code is at risk of being manipulated. So, it is essential to properly declare functions to the variables. It provides the following benefits:

• Makes the code neat and maintainable
• Allows easy splitting of files
•  Eases out the testing and maintenance process

Not using the controller AS Syntax

For assigning a model to the controller object, usually, the developers use $scope. But injecting the scope isn’t the right way to do it. Instead, using the controller as syntax is quite an effective and comparatively simpler method. Also, this syntax can be used in multiple ways in app development. But this syntax also has a drawback, that it provides confusing results while handling various nested scopes.

Unnecessary Use of jQuery

jQuery is commonly used for event-handling, for AJAX operations, and for making DOM manipulation easier. But it is advisable to first use the features available in Angular to the fullest and then use jQuery if required. Developers tend to first prefer jQuery without exploring options in Angular and this may result in unnecessary complications.

Improper Scope Binding

As we know, Angular uses the MVC model. Here, the scope is a set of built-in objects that consists of app data. Scope binds controller and view in the MVC model. At times, developers don’t follow the scoping rules provided by Angular which may result in issues in the app development process. The developers must properly assemble their scope objects.

Not using the Extension- Batarang

Batarang is a highly advantageous Google Chrome extension that aids in the development as well as the debugging process. But this extension is often ignored by the developers and not used to its fullest potential.

Putting too many Tasks for the Controllers

In the hurry to meet deadlines, developers may mix logic layers and allocate more tasks to controllers than necessary. This can result in a code that will execute more functions for a certain situation and may end-up in performance issues. For instance- having several event handlers or performing AJAX calls in controllers.

Ignoring Pre-launch testing

Needless to say, it is imperative to do adequate testing before an app is launched in the market. The app should be tested in cross browsers and different environments using tools like BrowserStack or LambdaTest if required. This helps in identifying the bugs if any. These bugs can be worked upon to deliver a successful app. Failing to do so can reduce the success rates to a great extent.

A few more Considerable Mistakes in Angular Development

•   Failing to use the event-handlers properly
•   Not optimizing the Angular app
•   Using the Isolated scope directives more than required, which results in several errors.
•   Using more Watchers than needed.
•    Heavy processing, that can lead to a frozen browser.
•    Overusing the Resolves that can increase loading times and slow down the app.

Final words:

In an Angular development company, it is quite normal for the developers to make some mistakes while building apps. Sometimes it is due to negligence, sometimes it is due to lack of experience and sometimes it is due to pressing timelines. Even experienced Angular developers tend to make critical mistakes at times during Angular mobile and web app development. But the knowledge of these errors and mistakes in advance can curtail them to a great extent and lead to time-saving and better app performance as well.

As per this report, Angular is the third most favorite choice of developers worldwide. This framework is known for its technical goodies and frequent updates. Each updated version intends to harness the latest technological innovations and improving the Angular experience. The proactive Angular team recently released yet another updated version, Angular11. The Angular11 release date is November14, 2020, and this release has strengthened Angular app development further.

Angular11 aims at addressing the bug-issues that have been raised by the community which ultimately intend to improve the developers’ experience. Furthermore, Angular11 ushers in a plethora of improvements, modifications, and deprecations for simplifying the developmental process. As such, every Angular App Development Company should be well versed with the prominent updates in Angular11.

This article will enlighten you about the new updates introduced in Angular11. So, get ready to embark on a journey into the world of Angular11.

The Notable Updates, Add-ons, Deprecations, and Modifications introduced inAngular11

Enhancements in Component Test Harnesses

Component test harnesses were initially introduced in the 9th update of Angular. It offered a sturdy and legible API surface that facilitated testing of Angular material. It enabled developers to interact with the components of Angular Material by making use of supported API during testing. However, this feature was only available for Angular Material so far. Angular11 has added harnesses for all the components. As a result, testing became much easier, and the developers now create sturdier test suites. Besides, Angular11 also introduces parallel functions, new APIs, and performance enhancements. The parallel function feature works with asynchronous actions during testing, as it allows developers to carry out several asynchronous interactions with components simultaneously. The manual change detection feature allows developers to disable the auto change detection mode while unit testing and gain a finer-grained access control of change detection.

Refurbished Hot Module Replacement (HMR) Mechanism

The existing mechanism of HMR (Hot Module Replacement), which enables Angular developers to replace modules without having to refresh the full browser, is refurbished in Angular11. Now, a CLI command is introduced so that the developers have to put so much lesser effort to configure HMR. To enable HMR, one simply needs to employ the ng serve command along with an hmr tag.

Operation Byelog Updates

Operation Byelog was one of the items when the Angular’s Roadmap was shared by the Angular team. The team’s objective was to put in lots of engineering efforts for triaging PRs and issues till they could clearly understand the needs of the huge community. Their initial intention of this goal was fulfilled with the release of Angular11. The reason is all issues have been triaged successfully in each one of the three existing monorepos. This will go on as a continual effort as new issues are reported. Moreover, all new issues that are reported will be triaged within a period of two weeks. This has minimized the size of the Angular backlog considerably. Additionally, this update has resolved some common concerns related to the router and forms.

Updates in Language Service Preview

The language service feature in Angular offers tools that ease out development and boost productivity as well. The erstwhile Language Service was based on View Engine. With Angular11, the Language Service is based on Ivy which is more robust and accurate as compared to the View Engine. After this update, the Language Service can accurately infer the generic sin templates as done by a TypeScript compiler.

Automatic Font-Inlining

Angular11 also introduces auto-inlining of fonts. This feature converts the icons and Google fonts to inline in the index HTML, each time the flag is set in angular.json under the build option. The fonts that are being linked and used with the app will be downloaded and inlined by the Angular CLI during compilation. For leveraging this update, you need to ensure the availability of connectivity while the build is running on CI. So, upgrade your apps to Angular11 for receiving this feature by default.

 Faster Builds

•   Support for TypeScript 3.9 has been dropped and Angular11 supports only TypeScript 4.0. This deprecation intends to accelerate builds.
•  The ngcc update procedure has become two to four times faster than before when dependencies are being installed.

Experimental Support for Webpack 5

Webpack is employed for compiling numerous files into one single file or bundle. Webpack5 is the most recent version, though not fully stable yet. But Angular11 offers experimental support for Webpack5 so that they can be used together for trying out new things. As per Angular11 release notes the Angular team intends to expand this experimental support once Webpack5 is stable, for achieving smaller bundles and speedier builds.

Migrating to ESLint

With Angular11, the use of the popular Angular linting tool TSLint and Codelyzer has been deprecated and TSLint is replaced by ESLint. The future versions won’t be providing default implementation to lint Angular projects and hence the Angular team advises migrating to ESLint. The team has devised a three-step migration process for moving to ESLint from TSLint. The steps are:

•   Adding relevant dependencies
•   Running the schematic convert-tslint-to-eslint on a project
•   Removing TSLint configuration and using only ESLint.

Other noteworthy Updates

·         The Angular roadmap is updated to keep the users informed about the on-going priorities. The team intends to put more effort so that developers can provide early feedback that can be included in the final release.

•   Modifications have been made in the builder phase reporting to enhance its usability.
•   The new CLI output updates, simplify creating logs and reading reports.
•   Angular11 introduces lazy loading with the help of named outlets which was not possible earlier.

Final Takeaway

Angular11 is loaded with groundbreaking enhancements and profitable add-ons. To reap its benefits all you need to do is update to this most recent version.

Reasons to choose Angular for architecting an Engaging and Attractive Website!

Traditional website designs fail to achieve the desired results any longer. Modern-day users expect websites to be not only intuitive and engaging but also visually attractive and decked up with rich features. One of the most befitting frameworks that satisfy this challenging requirement is Angular. Angular is an open-source JavaScript framework that came into being in 2009 and has been made future-ready by the release of frequent revamped versions by the Angular team, the latest one being Angular 10. This highly marketable framework excels in developing the creative components of a website and hence is a popular pick for website creators. Top brands such as Lego, PayPal, The Guardian, Weather, Netflix, etc. have leveraged Angular development services to build spectacular websites.

This article discusses the role of Angular in creating an engaging and visually appealing website design.

The role of Angular in creating an attractive and engaging website design

Have a look at the distinctive capabilities of Angular in the realm of web development!

Model-View-Controller approach

Angular’s MVC (Model View Controller) architecture splits the app into three distinct components – Model, View, and Controller. The Model maintains data, View displays necessary data and Controller acts as a bridge to connect View and Model. MVC approach eases out the task of Angular app developers while creating Single Page Applications and saves their time as well.

High Scalability

AngularJS development allows one to resize or alter components, modules, logical view, etc. through all stages of the developmental cycle. Therefore, the unidirectional flow is maintained even when developers create new functionalities or extend the existing logic.

Presence of Dependency Injection

Dependency Injection is a design pattern wherein an object bestows dependency on another object. With Angular, the dependencies run alongside their components and this enables the classes to obtain dependency from external sources. Consequently, a tree of dependency injectors is created which can be changed without the need to reconfigure its components. Moreover, owing to its hierarchical structure, it is clearly defined how alterations made to a certain element affects the function of other elements. Thus, this feature enhances performance and also speeds up development.

Lazy Loading

Lazy loading is a unique feature of AngularJS front-end development that enables asynchronous loading of JavaScript components when a particular route is activated. During this action, no other needless page or route is called for. The App Component is loaded as default by the app in the root URL, and the lazy module is loaded asynchronously when users navigate employing the command lazy/load-me.

Ability to create Declarative Interfaces

Angular’s ability to create a declarative UI, is another reason for its high adoption rate. Angular app development employs HTML in place of JavaScript to define the User Interface. HTML is much lesser complicated than JavaScript. Furthermore, owing to HTML usage, the UI components of an Angular web application gain intuitive and declarative properties. Hence, we do not need to manually create flows of the program, Angular’s declarative UI loads components automatically as per the defined page layout and the data. Therefore, the usage of Angular for building websites saves time as well as efforts of front-end developers.

Lightweight code

Since Angular is a framework, code is very precise. Development in Angular requires lesser coding as compared to JavaScript, CSS, and HTML. Moreover, the code is lightweight and readable.

SPA creation benefits

Angular is known for its capability to architect outstanding Single Page Applications as the Angular infrastructure supports journaling, routing, and template usage. Needless to say, SPAs possess a responsive web design and impart a native-like UX on the web.

Benefits of being a framework rather than a library

Angular is often compared to libraries like React.js, when talking about front-end development. But, since Angular is a framework and not a library; the set-up process becomes quicker which speeds up development. Additionally, the Angular eco-system possesses numerous self-libraries. Thus, Angular turns out to be far more beneficial than the libraries like React.js offering similar functionalities.

Ease of Testing

Angular’s capability to mock dependencies allows one to easily test any aspect of the web app starting from its User Interface to the business logic.  Also, the separation of modules reduces testing complexities and makes it possible for the users to load only those services that are needed.

Community Backing

The Angular framework has been created and is being maintained by the tech giant Google. As such, the Angular community is equipped with detailed documentation that covers all aspects related to its usage and fixing of issues.  Moreover, the community organizes global conferences, and hackathons involving IT professionals across the globe. It also solves the queries of Angular developers through online forums.

Wrap up

In a nutshell, Angular is stuffed with technical goodies that help one to create enticing and engaging websites speedily and in a cost-effective way. So, hiring an Angular App Development Company or Angular App Developers would be a wise decision for those planning to create captivating websites.

·       Rules for Angular Coding Styles

·       Top Security Practices to be followed in Angular

·       Routing and related Practices to be considered in Angular

·       How to prevent memory Leaks

·       How to use Template Directive

·       Utilization of noteworthy accessibility tool- Angular CLI

So, this blog is the continuation of Part I and here, you will get a glimpse of a few more important tips and tricks that ease out the development process in Angular as well as result in an impeccable end-product. Do read the Part I blog here.

Ideal Tips and Tricks for Angular App Development Process

Taking the advantage of ES6 features

In Angular, one of the JS versions-ECMAScript, gets updated with interesting features and functionalities in every release of Angular. ES6 is its latest version and has vital features available for efficient development.

‘let and const’ instead of ‘var’: By making use of ‘let and const‘ rather than ‘var‘ helps you prevent the issues related to var. Developers can use ‘let‘in a normal situation and the value doesn’t get changed, then ‘const’ should be in its place.

Spread operator: ES6 also comes with a ‘spread operator’ (depicted by three dots (…)) and is commonly used for arrays; but can also help in some common tasks. It helps ‘iterable‘ that can be, sets, strings, arrays, etc. to spread in the receiver.

Naming conventions

Naming conventions improves the readability and maintainability to a great extent. It helps the Angular app developers to find the required code, filenames, folders, etc. faster and makes the understanding easier. So, follow the below-mentioned naming conventions, as indicated by the Angular style guide:

·       Use consistent names for all the available symbols.

·       In the descriptive names, make use of dashes for separating words

·       Follow a certain pattern that explains the features of the symbol first and then its type. The recommended pattern- feature.type.ts. 

·       Make use of dots for separating the descriptive name from the type.

·       Also, make use of conventional type names like.component, .service, .module, .directive, .pipe, etc.

Maintaining the folder structure properly

It is of utmost importance to maintain a proper folder structure during Angular app development that can easily adapt to any modifications done during the development process. For instance:

— app

|– modules

|– home

|– [+] components

|– [+] pages

|– home-routing.module.ts

|– home.module.ts

|– core

|– [+] authentication

|– [+] footer

|– [+] guards

|– [+] http

|– [+] interceptors

|– [+] mocks

|– [+] services

|– [+] header

|– core.module.ts

|– ensureModuleLoadedOnceGuard.t

|– logger.service.ts

|

|– shared

|– [+] components

|– [+] directives

|– [+] pipes

|– [+] models

|

|– [+] configs

|– assets

|– scss

|– [+] partials

|– _base.scss

|– styles.scss

Using state management libraries

In Angular, state management is useful for the management of state transitions as it helps store the state of any kind of data. Several state management libraries like NGXS, NGRX, Akita, etc. are available and they come with different usages, purposes, states, etc. Amongst all of these, NGXS is one of the most widely preferred libraries since it has an easier learning curve and is highly stable as compared to others.

Using the right operators

Using appropriate operators in Angular is essential for various situations, especially when the flattening operators are used with the observables. So, follow the below ways for this:

·       Try to use mergeMap for handling all the emissions concurrently if you are willing to handle one emission after the other goes for concatMap.

·       Try to use switchMap when you want to ignore the previous emissions because of the new ones.\

·       For canceling the new emissions, try using an operator called exhaustMap.

Utilizing service workers for a responsive app

Service workers are especially helpful in making the apps interactive and responsive. They help in converting the SPAs into PWAs by integrating native features into them. They help in providing a native experience to the apps. They help in caching the version completely when the web pages are refreshed. Service workers also load the new or latest cached code in other tabs. They also download resources when the content is changed. Service workers can be used with any version of Angular above the fifth version.

Isolation of all the API hacks

For fixing the bugs and issues in the APIs, it is essential to have the hacks in components and also to isolate the API hacks in one place. This will help in keeping the hacks close to the API and thus, minimum code will have to deal with the un-hacked code. It also helps the Angular developers to find these hacks easily while fixing the bugs.

Using Smart vs. Dummy Components

Separating the smart and dummy components is another important practice that every Angular app development company should follow. Dummy components are utilized only for presentation purposes, so they do not know where the data comes from. In such scenarios, using smart components that can inherit the presentation logic of dummy components is the best approach.

Ensuring proper documentation as much as possible

Last but not the least, it is a great practice to document the code, methods used, variables, etc. wherever possible. This helps other Angular developers to understand the logic and purpose of the code; which in turn improves code readability and management. Also, documenting the role and the applications of every variable and method is a good practice.  For methods, every single parameter needs to be defined with multi-line comments specifying in brief about the tasks that the method accomplishes.
